Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hoisting mechanism for raising and lowering a pallet on which an automobile is mounted in an apparatus for parking an automobile.

[Prior Art] Various parking devices for parking a vehicle have been proposed. For example, in the multi-stage type, there is an elevator or condola type,
Also, in the two-stage type, a pallet on which an automobile is placed is moved up and down using a hydraulic cylinder, or a pulley is provided on the upper part facing the pallet, and one end of the wire rope hung on this pulley is used as the pallet and the other end is on the floor side. A method in which a main shaft that is rotated by the drive of a motor provided in the above and a plurality of take-up drums provided on a shaft that is transmitted by the main shaft are respectively wound up is generally used.

[Problems to be solved by the invention] Since the equipment cost of all the conventional multi-stage systems is high, when the two-stage system is used, the former hydraulic cylinder uses oil leakage when it is raised for a long time. However, there is a risk of falling due to the weight, and it is dangerous unless safety measures are used separately. In the latter case, the mechanism is complicated and the cost is high because it is dangerous if the winding drum is not motivated for all four wire ropes, and the biggest drawback is that the winding amount is large and the winding width or diameter is large. Use a drum. Therefore, the installation area becomes large. Further, after the pallet is lowered and the limit switch is operated, the winding drum is unwound due to the inertia of the motor, so that the rope can be loosened, and there is a problem that the winding operation is irregular when winding up.

[Means for Solving Problems] The present invention has been made in view of such circumstances and was devised to address this problem. That is, each wire rope having one end tied to a corner of a pallet, It is hung on a rotary pulley arranged on a beam opposite to the pallet, and the other end of this wire rope is passed through a fixed pulley arranged on the beam and a moving pulley provided at the end of the moving beam which also serves as a weight. The moving beam is fixed to the upper beam side, and the moving beam is attached to the center at one end thereof and attached to the winding drum supported on the machine base, and the other end of the wound wire rope is connected. A pallet elevating and hoisting mechanism for a parking device, which is characterized by connecting a brake motor mounted on a table and giving rotation.
One end of the wire rope bound to the pallet is fixed to the upper beam side, and a fixed pulley and a moving pulley installed on the beam are used between them, and the moving amount of the pallet is twice the moving amount of this moving pulley. Therefore, the purpose is to reduce the width or diameter of the winding drum to reduce the installation area, and yet another purpose is to make the beam with moving pulleys at both ends also function as a weight. The wire rope is constantly tensioned to prevent turbulent winding during operation and to prevent excessive impact.

[Operation] To put the car on the pallet with one end of the wire rope bound, and to raise the car on the pallet to the upper part and park it, drive the brake motor 14 on the base 11.
When the winding drum 12 is rotated in the winding direction, the wound wire rope 13 descends the beam 8 which also serves as a weight. At this time, movable pulleys 9 and 10 are provided at both ends of the beam 8 respectively, one ends suspended on the movable pulleys 9 and 10 are fixed respectively, and the other ends of the wire ropes 2 and 2 attached to the pallet 1 are movable pulleys. 9,10
Is lowered to raise the pallet 1. At this time, the pallet 1 is lifted by a moving amount that is twice the moving amount of the moving pulleys 9 and 10. The same applies when the pallet 1 is lowered. Therefore, the winding amount on the winding drum 12 can be small.

[Embodiment] Next, one embodiment of a pallet lifting / winding mechanism in a parking device according to the present invention will be specifically described with reference to the drawings.

Reference numeral 1 denotes a pallet for mounting an automobile, and each end of a wire rope 2 to be raised and lowered is bound to each corner. The wire ropes 2 are hung on fixed pulleys 3 and 4 facing the corners of the pallet 1, respectively. The fixed pulleys 3 and 4 are attached to beams 6 supported by columns 5, respectively. Further, double fixed pulleys 7, 7a are attached to the beam 6 apart from the fixed pulley 4 and are guided by hanging through the wire ropes 2, 2 suspended on the fixed pulleys 3 and 4.

Further, the wire ropes 2,2 that have passed through the double fixed pulleys 7,7a are hung on the movable pulleys 9,10 provided at the ends of the beam 8, and the tip ends are fixed to the beam 6 side by appropriate means.

The beam 8 with the movable pulleys 9 and 10 attached to the ends is at the center,
The other end of a wire rope 13 having one end attached to a winding drum 12 supported on a base 11 is bound.

The winding drum 12 that winds and rewinds the wire rope 13 is connected to and driven by a shaft 14a from a brake motor 14 mounted on the base 11.

[Effect] As described above, the present invention hangs each wire rope, one end of which is attached to the corner of the pallet, on the fixed pulley arranged on the beam facing the pallet, and the other end of the wire rope. Is fixed to the upper beam side through a fixed pulley arranged on the beam and a moving pulley provided at the end of the moving beam which also serves as a weight, and the moving beam is borne in the central portion on the machine base. Parking with one end attached to the take-up drum and the other end of the wound wire rope bonded to it, and the take-up drum connected to a brake motor mounted on the base to give rotation. A pallet elevating and hoisting mechanism in the device, in which the wire rope bound to one end of the pallet is fixed to the upper beam side at the other end, and the wire rope is provided between the fixed pulley and the end of the moving beam. Hanging on the pulley, the beam is heavy The one end is attached to the winding drum at the center and the other end of the wound wire rope is bound, and the pallet is moved up and down by the movement by the beam.The moving pulley is used on the beam side to wind up. As for the rewinding amount, the moving amount of the beam can be halved so that there is no waste, and since the moving amount is small, the width or diameter of the winding drum can be reduced. Therefore, the installation area may be small. Further, since the beam serves as a weight, the wire rope is always given tension, so that irregular winding at the time of starting can be prevented and an unreasonable impact does not occur. Further, at the same time, the winding is performed by driving the brake motor, so that the structure is simple and the like.
